在iOS中解压缩下载的文件 [英] Unzipping downloaded files in iOS

问题描述

我使用ASIHTTPRequest下载了一个zip文件，其中包含一个包含多个音频文件的文件夹.我试图用SSZipArchive和ZipArchive都解压缩文件，这两个都是基于minizip的.

Using ASIHTTPRequest, I downloaded a zip file containing a folder with several audio files. I tried to unzip the file with SSZipArchive and ZipArchive, which are both based on minizip.

编译代码时，出现以下错误:Undefined symbols for architecture i386: "_OBJC_CLASS_$_ZipArchive", referenced from: objc-class-ref in AppDelegate.o.

When I compile the code, I get this error: Undefined symbols for architecture i386: "_OBJC_CLASS_$_ZipArchive", referenced from: objc-class-ref in AppDelegate.o.

推荐答案

我使用了 ZipArchive 过去取得了成功.它相当轻巧，易于使用，支持密码保护，ZIP内的多个文件以及压缩和压缩功能.解压缩.

I've used ZipArchive with success in the past. It's pretty ligthweight and simple to use, supports password protection, multiple files inside a ZIP, as well as compress & decompress.

基本用法是:

NSString *filepath = [[NSBundle mainBundle] pathForResource:@"ZipFileName" ofType:@"zip"];
ZipArchive *zipArchive = [[ZipArchive alloc] init];
[zipArchive UnzipOpenFile:filepath Password:@"xxxxxx"];
[zipArchive UnzipFileTo:{pathToDirectory} overWrite:YES];
[zipArchive UnzipCloseFile];
[zipArchive release];
